If you broke the final shaft in the engine the crankcases must be split to replace it ..
That shaft is quite a big shaft are you sure you broke it..?.. Did you remove the clamps on the drive shaft rubber boot,slide the boot off either the engine or swingarm and with the rear wheels jacked off the ground turn the wheels and check what is or isn't turning..
